A summary of our recently and previously measured cross sections for 14.1 MeV neutron-induced reactions on lithium isotopes has been presented. These data of measurements of charged particles except protons are also compared with available data of other authors. Our data were taken with a counter telescope consisting of two gas proportional counters and silicon ΔE and E detectors. Measured energy spectra of deuterons and tritons from the three-body break-up reactions 6Li(n,d)5He and 7Li(n,t)5He, respectively, were analyzed by a simple final state interaction theory. Measured angular distributions for the above reactions as well as 6Li(n,t)4He and 7Li(n,d)6He were analyzed by DWBA calculations.
